Ezimotweni ezintsha zikagesi zamandla, ama-capacitor ayizingxenye ezibalulekile zokunquma impilo yokushayela imvamisa eguquguqukayo ekulawuleni amandla, ukuphathwa kwamandla, i-inverter yamandla kanye nezinhlelo zokuguqulwa kwe-DC-AC.I-capacitor ye-DC-LINKixhunywe nebhethri lokugcina amandla kanye neyunithi ye-inverter ukuze imunce ugesi ophezulu we-inverter kusukela ekugcineni kwe-DC-Link, okungavimbela ugesi ophezulu we-pulse ukuthi ukhiqizwe ku-impedance ye-DC-Link, ukuze ukuguquguquka kogesi ekugcineni kwe-inverter kube ngaphakathi kwebanga elamukelekayo; Ngesikhathi esifanayo, kungavimbela i-inverter ukuthi ithinteke yi-overshoot ye-voltage kanye ne-transient over-voltage ku-terminal ye-DC-Link.

Izincazelo zobuchwepheshe eziyinhloko zama-capacitor e-DC-Link yi-capacitance, i-standing voltage kanye ne-operating temperature range. Ngaphezu kwalezi zinkomba ezintathu eziyinhloko, esinye isibonakaliso esibalulekile sobuchwepheshe yi-equivalent series resistance (ESR) ye-capacitor. Ku-capacitor ye-DC-Link, i-ESR imele ukulahlekelwa yi-capacitor uqobo. Uma i-ESR iphansi, ukulahlekelwa kuncane, amandla okukhipha aphezulu, ukushisa kwe-capacitor kuyancipha, futhi ukusebenza kungcono.

Ama-capacitor efilimu asebenza kahle kakhulu e-CRE asetshenziswa kabanzi ezimotweni ezintsha zamandla, ekukhiqizeni amandla omoya, ezokuthutha ngesitimela nakwezinye izimboni. Phakathi kwazo,I-DKMJ-AP Ama-capacitor asetshenziswa ngokukhethekile ohlelweni olusha lokushayela imvamisa yezimoto zikagesi oluguquguqukayo, olunokumelana ne-voltage ephezulu, umthamo omkhulu, ububanzi bokusebenza kanye ne-ESR ephansi kakhulu.
